About Me
- Rob
- Cuddebackville, New York, United States
- I am a retired electronics engineer, educator, businessman and builder of micro hydro installations for fun and sometimes even profit. This one uses a pump/motor as a turbine/generator using a 200 ft waterfall in our back yard. It is currently producing 15KW. I will be tweaking it to take advantage of greater winter flows. It's not the product, but the process... I enjoy doing the most with the least. So this renewable energy source cost less than $2 per watt of capacity not counting any labor and engineering.

hi Robert,
Thanks for all the great info on PAT.
I found this and was wondering if you think it would work for 1000 gpm flow@100ft head ?

if it can be used as a turbine, any idea what kwh it might produce?
Hi Bill,
At 100 Ft head your water velocity would dictate a smaller diameter impeller to get the RPM up to 1800. A better match would be a 4X6X8 pump with perhaps a 20 to 30 HP 1800 RPM motor. You'll get maybe 5 to 8 KW. You could also try to find a 6 pole motor to put on this pump to bring the max power rpm down to 1200 RPM.

Your blog keeps getting better and better! Your older articles are not as good as newer ones you have a lot more creativity and originality now keep it up!
I am the sort of guy who loves to seek recent things. Currently I am fabricating my personalized pv panels. I am managing it all by myself without the help of my staff. I'm using the net as the only way to acheive that. I encountered a truly amazing site that explains how to build solar panels and so on. The internet site explains all the steps required to solar panel construction.
I'm not exactly sure about how correct the data given there iz. If some guys over here who had xp with these things can have a see and give your feedback in the site it will be awesome and I would really appreciate it, cause I really passion solar panel construction.
Thanks for reading this. You guys rock.
I want not concur on it. I assume nice post. Particularly the appellation attracted me to be familiar with the unscathed story.
